O3-5 Family Health Climate, parental outcome expectations and physical activity of children in primary-school age

Abstract Introduction Children's health related behaviors, such as physical activity develop are maintained in the family environment. A large amount of studies examined different family influences on children's health behaviors. It has been shown that the Family Health Climate (FHC) (Niermann et al., 2015), and parents' general beliefs and expectations regarding children's PA are related to children's behaviour (Fredricks & Eccles, 2004). However, there is a lack of studies that examined changes in these variables over time and their relation to changes in children's physical activity. The aim of this study was to investigate a) if FHC and outcome expectations change from first to fourth grade in primary school and b) how they are related to decrease or increase of children's physical activity. Methods 380 consulted parents of primary-school age children (46,6 % male) continuously answered questions about their PA-related outcome expectations, FHC (predictor) and daily PA (outcome) of their children over four school years, starting 2014 with first grade (t1), third grade (t2), fourth grade (t3) in Leipzig, Germany. Repeated measures ANOVA were used to analyse changes over time. Results Analysis showed no significant difference for FHC (F(1.96, 743.27) = 1.92, p =.15) an for parent's PA-related outcome expectations (F(1.98, 749.58) = 0.097, p = .91). Children's daily PA decrease significant over time (t1 to t3) (.04, 95%-CI[0.004, 0.343], p = .043). Conclusion The results indicate stability of the FHC and parents' outcome expectations during primary school. In contrast, physical activity decreases over time, which is in line with previous studies. In further analyses we will examine how FHC and parents' outcome parents outcome expectations are related to changes in physical activity. In addition, future analyses should be performed gender-specific.


Introduction
Children's health related behaviors, such as physical activity develop are maintained in the family environment. A large amount of studies examined different family influences on children's health behaviors. It has been shown that the Family Health Climate (FHC) (Niermann et al., 2015), and parents' general beliefs and expectations regarding children's PA are related to children's behaviour (Fredricks & Eccles, 2004). However, there is a lack of studies that examined changes in these variables over time and their relation to changes in children's physical activity. The aim of this study was to investigate a) if FHC and outcome expectations change from first to fourth grade in primary school and b) how they are related to decrease or increase of children's physical activity. Methods 380 consulted parents of primary-school age children (46,6 % male) continuously answered questions about their PA-related outcome expectations, FHC (predictor) and daily PA (outcome) of their children over four school years, starting 2014 with first grade (t1), third grade (t2), fourth grade (t3) in Leipzig, Germany. Repeated measures ANOVA were used to analyse changes over time.

Conclusion
The results indicate stability of the FHC and parents' outcome expectations during primary school. In contrast, physical activity decreases over time, which is in line with previous studies. In further analyses we will examine how FHC and parents' outcome parents outcome expectations are related to changes in physical activity. In addition, future analyses should be performed gender-specific.

Background
The rise in childhood overweight and obesity worldwide demands effective health promotion and obesity prevention programmes, especially targeting socially disadvantaged areas. The aim of this study is to examine the effectiveness of a revised parental support programme, promoting physical and a healthy diet, and on preventing overweight among children in disadvantaged areas.
ectiveness of this programme will be compared to school routines in a parallel group cluster randomised ed trial. The 6-month programme included: 1) A health information brochure; 2) School nurses conducting motivational interviewing with parents; 3) Classroom activities and home assignments for children; 4) A self-test for type-2 diabetes risk for parents. Seventeen schools were enrolled including 352 six-year-old children (155 intervention/197 control). Physical activity and sedentary time were measured by accelerometry. Dietary intake was assessed by a newly developed mobile phonebased photo method. Weight and height were measured by trained researchers. All outcomes were measured at baseline and at 6 and 18 months post baseline. Parental level of education was self-reported, and the highest level achieved by either parent was used as an indicator of socioeconomic position (SEP). A mixedeffect regression analysis will be performed to evaluate the effectiveness of the programme.

Results
After the intervention, when adjusting for sex and parental education, the intervention group showed 6.4 mins more moderate to vigorous physical activity (MVPA) during weekdays than the control group (p = 0.03). No significant effect on MVPA was detected during weekends (p = 0.47). Further, no significant effect was detected on time spent sedentary during weekdays (p = 0.12) nor during weekends (p = 0.78). According to IOTF classifications, 9.6% of the children had obesity, 16.4% overweight, 4.4% underweight and 69.6% normal weight. Results on changes in BMI, and dietary intake at 6 months will be presented.

Conclusions
The results from the evaluation of this parental support programme will add to the knowledge and advance intervention and implementation research in the Swedish/Nordic context relating to prevention of overweight and obesity in
